An area of low pressure developed over the Gulf Stream just offshore of North Carolina. Rapidly deepening, it tracked northeastwards and then northwards, pushing a cold front across Bermuda in the pre-dawn hours of Tuesday morning. The cold front brought showers and thunderstorms that produced over a half inch of rain to the island along with strong winds. A post-frontal trough produced some isolated showers overnight and this morning.Now a strong area of high pressure is building in over the northwestern Atlantic. The influence of this high should remain the dominant player in Bermuda’s weather at least into mid-week next week.

Tomorrow the high is expected to be centered to the northwest of the island producing light-moderate northeasterly winds. As the high slides eastward on Friday, winds shift to a more eastward direction. The high is then elongated into a ridge and forced southwards as a cold front pushes into the area from the north. Winds veer through to west over the weekend as this happens. There will then be a chance for some showers on Monday as the front stalls to the north of the island and increases winds moderate-strong. High pressure could remain in control, however, keeping us dry until the next frontal system pushes in later next week. Expect mainly dry conditions with varying cloud and winds as high pressure remains in control for at least the next 5 days. Keep an eye on next Monday’s front for chances of some unsettled weather – if it gets a little closer to the island those chances may increase, and the opposite is true.
